WILLIAM HAAS, OF SAN FRANCISCO, CALIFORNIA.

STREET-SKWEEPING MACHINE.

' SPECIFICATION forming-part of Letters Patent No, 378,002, dated February 14, 1888.

Application filed January 27, 1885. Renewed October 15, 1887. `Serial No. 252,500. (No model.)

To all whom it may concern: Y

Be it known that I, WILLIAM HAAs, a citizen of the United States, residing at San Fran-l cisco, in the county of San Francisco, State of California, have made and invented certain new and useful Improvements in Street-Sweeping Machines, of which the following is a speciflcation.

My improvements relate to machines forl dumping apparatus.

Referring to the accompanying drawings by figures and letters, Figure 1 is a vertical section in elevation of my improved ystreetsweeper, the section being taken longitudinally through the middle of the` box and the brush-cylinder. Fig. 2 is a plan or top view.

Fig. 3 is a longitudinal section similar to Fig.

l, but showing the bottom ofthe receptacle in the position of discharge and the brush-cylinder raised.

The box Ais open at the tail end and closed at the sides and front. 1t is mounted on four wheels, W W, and is suspended from the front axle and set upon a bent axle at the rear to bring the bottom at suitable distance from the ground. 1

B B are pivoted sections that form the bottom of the receptacle, and C is an apron, also pivoted or hinged to lift and drop, which forms the inclined apron to catch the Vsweepings from the brush and direct them upward into the receptacle. The rods b b, that constitute the pivots of these sections, extend beyond the box at one side and have each an arm or lever, b2. These levers are connected one to the other and the foremost one to a hand-lever, E, at the front of the vehicle, by links or connecting-rods e c e2, in such :manner that the movements of the lever-handle will bring the sections up into horizontal position and as in Fig. l, or will tilt them, asin Fig. 3.

line with one another to form a close bottom,

The last section of the bottom and the apron C move together, and are operated by thesame lever, E.

A brush-cylinder, F, of any suitable construction, is mounted in a swingingframe, G,

that is suspended at g g from the axle, andcarries at the front a counter-weight, H, to balance the brush.

The shaft Ex of the brush-cylinder has gearwheels I I on the outer ends, which engagev with drivers J IJ, secured to the tractionwheels. therefore produced forward and upward to throw the dirt upon the inclined apron. l

The swinging frame` and the-apron are con- The motion ofthe brush-cylinder is j nected together by the rod K, so that the brush is thrown down and up and into or out of action simultaneously with the movement of the apron and by the same operating-handle, E, at the front. By this construction it will be seen that when the machine has been carried to the desired place the operator, by simply pressing forward thelever E, will cause the apron and brush to rise vand the pivoted bottom sections, B, to fall simultaneously and dump the load, and thereby throw the brush up out of operation. VBy reversing the move-k ment of the lever E partsare all returned to their normal and'operative position.

The sides of the box are tapering from the rear to the front, as shown in the plan, Fig. 2, and each tilting section/ is therefore wider at the 'discharge end than it is at the forward end. This facilitates the discharge of the dirt and prevents choking or clogging.

As thus constructed, my improved sweeper is Ycapable of being driven and managed by one person. v

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. Inv'a street-sweeper, the combination of Athe receptacle A, having its bottom formed of tilting sections B, the hinged apron C, the operating hand-lever E, levers b, and con'nections e e c2, and the swinging frame G, carrying the brush-cylinder F and counter-balance.y H, and connected with the hinged apronV by the rod, as a means of moving the frame to In witness whereof I have hereunto set my bring the brush into and ont of action. hand and seal.
